Electron Temperature Dependence of the Dissociative Recombination Coefficient of Molecular Argon Ions Ar+2 with Electrons

A dual mode (TM010 cylindrical cavity/cylindrical waveguide) microwave apparatus is used to study the ion mobility and dissociative recombination of molecular argon ions with electrons in the afterglow period of a d.c. glow discharge as a function of electron temperature when electrons were heated by microwaves up to Te ≤ 10300K, with T+ = Tgas = 300K. The electron temperature dependence of the total rate coefficient of dissociative recombination may be represented by α (Ar+2) = (8.1 ± 0.5) × 10–7[300/Te(inK)]0.64cm3s–1 which is in very good agreement with most previous experimental results but not with the recent theoretical calculations (© 2011 WILEY‐VCH Verlag GmbH & Co.
